FIELD OF THE INVENTION
[0003] The present disclosure relates generally to an evaporative
air cooler.
BACKGROUND
[0004] Evaporative personal air coolers are commonly used to cool
air in a home, office, or other hot, dry air environment.
Conventional evaporative air coolers operate by drawing ambient air
into the evaporative air cooler and direct it through a
water-soaked filter device. As warm air passes through the
water-soaked filters, heat from the ambient air evaporates water
trapped in the water-soaked filter device. The evaporated water
cools the air as it leaves the water-soaked filter device and exits
the evaporative air cooler.
[0005] Conventional evaporative air coolers typically include a
fan, a filter device, and a water distribution system. The fan
draws outside air into the evaporative air cooler, pushes it
through the filter device to produce cooler air, and then pushes
the cooler air out of the evaporative air cooler. More
specifically, the water distribution system provides water to the
filter device so that the filter device becomes water soaked. The
water distribution system includes a water pump that draws water
from a reservoir and distributes the water to a bottom surface of
the filter device which soaks upwards. Depending on the type of
filter and the amount of water in the reservoir, the water may
travel only partially up the filters. If the filters are not fully
soaked with water, the evaporative air cooler is less effective at
producing cooler air. Filter devices typically include filters made
of a paper-like material that have to be replaced often. The
filters cannot be reused or easily cleaned.
[0006] Some of the water distributed to the filter device
evaporates as air flows through the filters. The water in the
reservoir depletes as the evaporative air cooler operates due to
the evaporation. Any unabsorbed water that recirculates within the
evaporative air cooler returns to the reservoir. When the reservoir
is fully depleted of water but the filter device is soaked with
water, the evaporative air cooler can still produce cooler air, but
it becomes less effective. The evaporative air cooler will cease
producing cooler air when the filter device is dry. Thus,
additional water must be constantly added to replace the water that
has been evaporated.
[0007] It typically takes conventional evaporative air coolers a
considerable period of time to begin cooling air because the filter
device must soak up water from the reservoir before the cooling
process can begin. In other words, conventional evaporative air
coolers do not instantly produce cooler air.

DETAILED DESCRIPTION
[0051] The following description is merely exemplary in nature and
is not intended to limit the disclosure in its application or uses.
For purposes of clarity, the same reference numbers are used in the
description and drawings to identify similar elements.
[0052] The present disclosure relates generally to an evaporative
personal air cooler by which it draws in ambient air, cools the
ambient air, and blows out the cooled ambient air. In this
disclosure, the evaporative personal air cooler may be referred to
as an evaporative air cooler, a portable evaporative air cooler, or
any other desirable air cooler.
[0053] The evaporative air cooler 10 can include a housing 20
having a power adapter, a water tank 40, a v-shaped shroud 44, a
fan 48, a drawer 50, and a filter structure 56.
[0054] FIG. 1 illustrates an exemplary evaporative air cooler 10.
The evaporative air cooler can include the housing 20 with a top
face 22, a bottom face 24, and four lateral faces, such as a front
face 26, a back face 28, and side faces 30. The housing 20 can be
formed as a cube housing, a rectangular housing, or any other
desirable configuration or shape. The housing 20 can be formed from
plastic or any other desirable material.
[0055] The top face 22 can include a lid, such as a hinged lid 32.
FIG. 2 illustrates the evaporative air cooler 10 with the hinged
lid 32 opened for access to the water tank 40. The hinged lid 32
can be located along a front portion of the top face 22. The hinged
lid 32 can include a lid tab 76 positioned in the front of the
hinged lid 32 or any other desirable location. The hinged lid 32
can be opened to allow for water to fill the water tank 40. For
example, a user can pull the lid tab 76 upward to open the hinged
lid 32. The hinged lid 32 can be formed from plastic or any other
desirable material. The opening to the water tank 40 can be any
desirable opening and is not limited to the hinged lid 32 described
in this disclosure.
[0056] The top face 22 can also include buttons, such as a power
button 34, a light button 36, or any other desirable button. The
top face 22 can also include one or more lights, such as an
indicator light 38 or any other desirable light or indicator. The
indicator light 38 may be used to indicate a fan speed, a level of
water located within the water tank 40, whether filters 58 should
be replaced, or any other desirable indication. For example, at a
high speed, all three indicator lights 38 can be powered ON. At a
medium speed, two indicator lights 38 can be powered ON. At a low
speed, one indicator light 38 can be powered ON. In one embodiment,
if the power button 34 is held down for at least three seconds, the
indicator lights 38 can all turn off. The indicator light 38 may
include one or more lights. The indicator light 38 may display a
blinking light or a solid light. The indicator light 38 may display
different light colors, such as green, red, amber, or any other
desirable color.
[0057] The power button 34 can be configured to activate (e.g.,
power ON), change the fan speed of the fan 48, and deactivate
(e.g., power OFF) the evaporative air cooler 10. For example, when
the power button 34 is first activated, the indicator light 38
(e.g., three indicator lights 38) can turn ON, the fan 48 can turn
ON (e.g., to a high speed), and an aperture 42 positioned in the
water tank 40 can allow water to flow out of the tank 40 to begin
the evaporative air cooling process. When the power button 34 is
activated a second time, one of the indicator lights 38 can turn
OFF (e.g., two indicator lights 38 remain ON), the fan speed can
decrease (e.g., to a medium speed), and the aperture 42 can allow
less water to flow out of the tank 40. When the power button 34 is
activated a third time, one of the indicator lights 38 can turn OFF
(e.g., one indicator light 38 remain ON), the fan speed can
decrease (e.g., to a low speed), and the aperture 42 can allow less
water to flow out of the tank 40. When the power button 34 is
activated a fourth time, one of the indicator lights 38 can turn
OFF (e.g., no indicator lights 38 remain ON), the fan 48 can turn
OFF, and the aperture 42 can stop the water from flowing out of the
tank 40. In other words, the power button 34 can be activated to
deactivate, or power OFF the evaporative air cooler 10. In one
embodiment, when the power button 34 is activated (e.g. pressed
downward) for three or more seconds, it can turn OFF the indicator
lights 38 and the evaporative air cooler 10.
[0058] The fan 48 can be wired to the evaporative air cooler 10.
The wires can be soldered to electrically connect the fan 48 to the
evaporative air cooler 10, or attached in any other desirable way.
The wires can be hidden in a wire compartment or any other
desirable compartment within the evaporative air cooler 10.
[0059] A light, such as a blue LED light, can be positioned within
the water tank 40, such as beneath the power button 34, or any
other desirable area for illuminating the water tank 40. The light
can be used for ambiance, as a nightlight, or any other desirable
purpose. The light may be on by default when the evaporative air
cooler 10 is powered ON. The user can lower the brightness of the
light or turn OFF the blue LED completely by pressing the light
button 36. For example, after the power button 34 is pressed, the
light is on a high brightness mode. When the user presses the light
button 36 for a first time, the light can reduce its brightness
(e.g., to a low brightness mode). When the user presses the light
button for a second time, the light can turn OFF. In one
embodiment, if the light button 36 is activated for a minimum
amount of time (e.g., three seconds), an illumination setting can
be selected and/or locked.
[0060] As illustrated in FIG. 2, the bottom face 24 can include
feet 62 that project outward from the bottom face 24. The feet 62
can be configured to elevate the evaporative air cooler 10 from a
surface it is placed on. The feet 62 can also be configured to
prevent the evaporative air cooler 10 from damaging the surface.
For example, when sliding the evaporative air cooler 10 across the
surface, the feet 62 can prevent the scratching of the surface. The
feet 62 may be formed from rubber, plastic, grips, or any other
desirable material. The bottom face 24 can include a plurality of
feet 62. The feet 62 may be formed as circular feet 62, ovular feet
62, square feet 62, rectangular feet 62, or any other desirable
shape. The feet 62 can be positioned toward each corner of the
bottom face 24, or any other desirable location. In an alternative
embodiment, the bottom face 24 does not include feet 62.
[0061] The lateral faces can include a front face 26, a back face
28, and two side faces 30. The lateral faces can be positioned
between the top face 22 and the bottom face 24 about their outer
perimeters. The lateral faces can be positioned adjacent each
other. The lateral faces can include a framed portion 64 and a face
portion 66. The framed portion 64 can be positioned about a
perimeter of a lateral face, wherein the face portion 66 is
positioned within the framed portion 64. For example, the side
faces 30 can include an upper portion 68, the framed portion 64
positioned adjacent the upper portion 68 and along the side and
bottom edges of the side faces 30, and a face portion 66 positioned
within the framed portion 64.
[0062] As illustrated in FIG. 3, the front face 26 can include an
upper portion 68 and a framed portion 64 positioned adjacent the
upper portion 68 and along the side and bottom edges of the top
face 22. The front face 26 can also include an outlet vent 52
positioned within the framed portion 64. The outlet vent 52 can
include a plurality of vents 70, an air direction tab 72, and a
filter drawer tab 120. The plurality of vents 70 can include a
fixed vent 122 and an adjustable vent 124. For example, the fixed
vent 122 may be positioned as the lowest vent 70 on the outlet vent
52. The remainder of the plurality of vents 70 may consist of the
adjustable vent 124. Each of the plurality of vents 70 can be
positioned horizontally in the outlet vent 52. Each of the
adjustable vents 124 can be movably connected to the air direction
tab 72. The air direction tab 72 can be positioned to direct air
flowing from inside the evaporative air cooler 10 through the
outlet vent 52. For example, if the air direction tab 72 is
positioned upward, the adjustable vents 124 may be positioned in an
upward position to direct the airflow upward. Similarly, if the air
direction tab 72 is positioned downward, the adjustable vents 124
may be positioned in a downward position to direct the airflow
downward. If the air direction tab 72 is positioned in a center
position, the adjustable vents 124 may be positioned in a
substantially horizontal position, directing the air to flow
horizontally from the evaporative air cooler 10. The air direction
tab 72 can direct the air to flow at any angle between the downward
and upward angles.
[0063] The face portion 66 of the front face 26, such as the outlet
vent 52, can be connected to an internal assembly 74 that is
removable from the housing 20. As illustrated in FIGS. 4 and 5, the
internal assembly 74 of the evaporative air cooler 10 can include
the filter structure 56 including filters 58, the drawer 50
including a water tray 54. The internal assembly 74 can fit tightly
around the circumference of the fan 48. For example, the internal
assembly 74 can form a seal around the fan 48 to direct air out of
the evaporative air cooler 10. The internal assembly 74 can be
configured to increase the force of the air as it exits the
evaporative air cooler 10 to increase the cooling effect of the
evaporative air cooler 10. The internal assembly 74 may also be
configured to decrease noises produced during operation of the
evaporative air cooler 10. For example, the seal, such as an
airtight seal, reduces the amount of air escaping from the
evaporative air cooler 10 and reduces air vibrating off of other
components or the walls of the evaporative air cooler 10.
[0064] The drawer 50 can be attached to the outlet vent 52. The
outlet vent 52 can be removed from the evaporative air cooler 10.
For example, the fixed vent 122 can include a filter drawer tab
120. The user can pull on the filter drawer tab 120 to remove the
outlet vent 52 from the evaporative air cooler 10. The outlet vent
52 can have one or more tabs or any other desirable device for
removing the outlet vent 52 from the evaporative air cooler 10. An
interior side of the side faces 30 can include a drawer guide 108.
The drawer guide 108 is configured to assist the user in slidably
removing and inserting the drawer from and into the housing 20.
[0065] The drawer 50 can include the water tray 54. The water tray
54 can be positioned in the drawer 50. The water tray 54 can be
formed at the bottom of the housing 20. The water tray 54 can be
angled for any liquid on the water tray 54 to flow in a direction
toward the filter structure 56. For example, the water tray 54 can
be higher toward a back end 78 of the drawer 50 than toward the
front end 80 of the drawer. The water tray 54 can be configured for
cleaning. For example, when the drawer 50 is removed from the
evaporative air cooler 10 and the filter structure 56 is removed
from the water tray 54, the water tray 54 can be easily accessible
for cleaning. The user can wipe down and dry or otherwise clean the
water tray 54. Cleaning the water tray 54 may result in less mold
or other bacteria.
[0066] The drawer 50 can be configured to support the filter
structure 56. The filter structure 56 can be removably attached to
the drawer 50. The drawer 50 can have a drawer notch 128 to secure
the filter structure 56 in place. For example, the filter structure
56 can be placed on a top surface of the water tray 54 between the
outlet vent 52 and the drawer notch 128.
[0067] As illustrated in FIGS. 6A-6C, the filter structure 56 can
include a filter frame 82 and a plurality of filter holders 84
attached to opposing sides of the filter frame 82. In one exemplary
embodiment, as illustrated in FIG. 6C, the filter frame 82 can
include a top opening 86 and a bottom opening 88. The top opening
86 can be configured to allow for a mist 118 to contact top
portions 112 of the filters 58. The bottom opening 88 can be
configured to allow for the mist 118 and/or liquid, such as water,
to contact bottom portions 114 of the filters 58. For example, if
liquid has collected in the water tray 54, the liquid can contact
bottom portions 114 of the filters 58. The sponge material 60 of
the filters 58 may soak up the liquid. The sponge material 60 may
also soak up the mist 118 as it contacts the filters 58. The filter
holders 84 can define a plurality of holes, or filter openings 90.
Each filter opening 90 can be configured for one filter 58 to be
positioned within it. The filter holders 84 can be positioned
substantially parallel to each other within the filter structure
56. The filter holders 84 can be configured to hold the filters 58
in place. The filters 58 can be positioned substantially parallel
to each other and to opposing sides of the filter structure 56. The
filter holders 84 can be configured with space, such as air gaps
92, between each filter holder 84 to allow for the mist 118 and/or
liquid to contact the filters 58. The air and/or the mist 118 may
also flow through the air gaps 92 and out of the evaporative air
cooler 10. The filter structure 56 can be formed from plastic,
metal, or any other desirable material.
[0068] As shown in FIGS. 4-6, the filter structure 56 can include a
plurality of filters 58 mounted vertically. The filters 58 can be
positioned parallel to the direction of airflow. The filters 58 can
be formed from a sponge material 60. The filters 58 can be soaked
prior to use. For example, the user can pull the filter drawer tab
120 on the outlet vent 52 to pull out the internal assembly 74,
including the drawer 50, water tray 54, and the filter structure
56. The internal assembly 74 can slide out from within the
evaporative air cooler 10. The filter structure 56 can be removed
from drawer 50. The filter structure 56 can be placed in liquid,
such as water, placed under running water, or any other desirable
method to soak the filters 58. After the filters 58 are wet, the
filter structure 56 can be placed in the freezer, or any other
desirable cooling device. If the wet filters 58 are frozen, the
cooling effect of the evaporative air cooler 10 can be enhanced.
When complete, the user can put the filter structure 56 on the
drawer 50 and slide the internal assembly 74 back into the
evaporative air cooler 10. If the filters 58 are pre-moistened, the
initial cooling effect can increase because air travels through the
wet filters 58 when the evaporative air cooler 10 first starts
running. If the filters 58 are not presoaked, the evaporative air
cooler 10 can produce cool air, but it may not be at capacity.
[0069] The filter structure 56, including the plurality of filters
58, can be constructed of sponge material 60, plastic and sponge
material 60, or any other desirable material. The filter structure
56, together with the filters 58, can be configured for cleaning.
For example, the plastic and sponge material 60 can be cleaned
using various methods, such as handwashing, soaking, dishwasher, or
any other desirable method. The filter structure 56, including the
filters 58, can be sanitized. For example, the filter structure 56,
including the filters 58, can be sanitized in a microwave or any
other desirable method. The filters 58 can be handled, washed, and
used more vigorously than filters formed from paper material. The
filters 58 can be reusable, used longer while wet, re-moistened and
re-dried, and have an overall longer lifetime and usability than
paper filters. The filter structure 56 can be replaced, for
example, after three to six months of use.
[0070] The evaporative air cooler 10 can also be powered ON without
water in the water tank 40 to dry out the filters 58 and the
interior of the evaporative air cooler 10. For example, if a user
plans to not use the evaporative air cooler 10 for an extended
period of time, the user can empty the water tank 40, press the
power button 34 to turn the evaporative air cooler 10 ON to the
high mode for a period of time, such as for four hours.
[0071] The back face 28 can include the upper portion 68 and the
framed portion 64. The back face 28 can include a power port for
the power adapter. The power adapter includes a cord with a first
power adapter plug on one end that is configured to plug into the
power port and a second power adapter plug on the opposite end of
the cord that is configured to plug into an outlet, such as a wall
outlet or a power strip. The power port can be located in the upper
portion 68 of the back face 28 or any other desirable location on
the evaporative air cooler 10. In another embodiment, the
evaporative air cooler 10 can be powered using batteries or another
power source.
[0072] The back face 28 can also include a grate 94. The grate 94
can be positioned within the framed portion 64. The grate 94 can
include a plurality of ribs positioned horizontally or vertically
along the back face 28. As shown in FIGS. 5 and 6, the grate 94
includes both horizontal ribs 96 and vertical ribs 98 that define a
plurality of grate openings 100. The plurality of grate openings
100 are configured to allow air to flow from outside the
evaporative air cooler 10 to inside the evaporative air cooler 10.
The grate 94 may also have a cord guide for securing the cord of
the power adapter in place. The cord guide may be located along one
side of the grate 94 and adjacent to the framed portion 64, or any
other desirable location. The grate 94 may have one or more cord
guides tabs. Additionally, some of the horizontal ribs 96 may be
shorter to allow for the cord to be positioned flush with the
horizontal ribs 96.
[0073] As illustrated in in FIGS. 7 and 8, the fan cover assembly
102 can include the grate 94, the fan 48, and a fan cover 46. The
fan cover assembly 102 can be configured to reduce vibration and
other movement within the evaporative air cooler 10. By doing so,
the fan cover assembly 102 can reduce the noise of operation of the
evaporative air cooler 10. The fan cover assembly 102 can also
efficiently direct airflow. For example, the fan cover assembly 102
can effectively direct air outward from the evaporative air cooler
10.
[0074] For example, the fan 48 can direct airflow from the back
face 28 toward the front face 26. The fan 48 can be positioned
inside the housing 20 between the grate 94 and the fan cover 46.
The fan cover 46 can be configured to further direct the airflow.
For example, the fan cover 46 can provide an optimal volume of air
flow for the size and type of the evaporative air cooler 10. The
fan cover 46 can be configured to maximize the technical and
electrical specifications of the fan 48.
[0075] The user can control the speed of the fan 48. For example,
the user can press the power button 34 to toggle the fan speed
between three different speeds (e.g., high, medium, and low
speeds). Changing the fan speed can change the water flow rate
through the aperture 42. The change in the water flow rate can be
proportional to the change in the fan speed. At the high speed, the
water flow rate can be at a high rate. At the medium speed, the
water flow rate can be at a medium rate. At the low speed, the
water flow rate can be at a low rate.
[0076] Thus, the misting structure 104 can be configured to produce
a variable volume of the mist 118. The volume of the mist 118
produced can be based on the fan speed. For example, as the fan
speed increases, the volume of the mist 118 can increase. The
increase in the volume of the mist 118 may allow for an optimal
amount of moisture to enter into the air, which can result in a
better cooling effect. As the fans speed decreases, so may the mist
volume.
[0077] For example, when the power button 34 is pressed, the
evaporative air cooler 10 can turn on. The fan 48 can begin
spinning, and the mist 118 can begin to spray from a misting
structure 104. The default fan speed can be the high speed when the
evaporative air cooler 10 is first powered ON, or any other
desirable fan speed. The user can adjust the cooling effect of the
evaporative air cooler 10, including the amount of the mist 118
and/or the airflow speed using the power button 34. The user can
adjust the airflow direction (e.g., from top to bottom) using the
air direction tab 72 on the outlet vent 52. The power button 34 can
be pressed again to turn off the evaporative air cooler 10.
[0078] As illustrated in FIG. 7, the v-shaped shroud 44 can be
positioned on an underside of the top internal panel 110 to allow
liquid to transform into the mist 118. The top internal panel 110
can be a wall between the evaporative air cooler 10 and the water
tank 40, the bottom of the water tank 40, or any other desirable
structure. The v-shaped shroud 44 can be configured to distribute
the mist 118 evenly toward the filters 58. An even distribution of
liquid on the filters 58 provides an effective cooling effect for
the user. The v-shaped shroud 44 can be configured to maximize
airflow to the user.
[0079] For example, the v-shaped shroud 44 can extend from the
bottom of the water tank 40 into the evaporative air cooler 10. The
fan 48 used with the v-shaped shroud 44 can turn the liquid into
the mist 118 and direct the mist 118 toward the filter structure 56
and filters 58. Some of the mist 118 may evaporate, and some of the
mist 118 may travel between the sponge material 60 and through
outlet vent 52 to cool the air outside of the housing 20. Some of
the mist 118 can soak into the sponge material 60, allowing for
later evaporative cooling. Some of the mist 118 can fall into the
water tray 54, where it can collect and turn into liquid. The
liquid can be absorbed into the filters 58 via capillary action, to
allow for additional evaporative cooling. The water tray 54 can be
constructed with a slight angle. The slight angle can cause excess
or unabsorbed liquid to flow toward the filters 58. The excess
liquid can be absorbed by the filters 58 and wicked up, allowing
for a longer cooling effect. Also, wicking up the excess water can
result in a reduction of water spills if the evaporative air cooler
10 is moved or the drawer 50 is removed from the evaporative air
cooler 10.
[0080] As illustrated in FIGS. 4 and 9, the housing 20 can include
a container or a tank, such as the water tank 40 positioned beneath
the top face 22. Liquid, such as water, can be placed into the
water tank 40. For example, when the hinged lid 32 is open, liquid
can be poured into the water tank 40 using a pitcher or any other
desirable means. The water tank 40 can have an opening, such as the
aperture 42, to release liquid from the water tank 40 into the
evaporative air cooler 10. The aperture 42 can be positioned in the
bottom of the water tank 40. The aperture 42 can be positioned
between the v-shaped shroud 44 and the front face 26. More
specifically, the aperture 42 can be positioned between the
v-shaped shroud 44 and the filter structure 56.
[0081] The evaporative air cooler 10 can use a two-stage cooling
for its cooling process. The first stage can incorporate a misting
structure 104. The misting structure 104 can include a microporous
mister, such as a mister 106. The second stage can incorporate a
filter structure 56 having an evaporative sponge filter, such as
filters 58 made from sponge material 60. The combination of both
stages can produce an instant cooling effect and a prolonged
cooling effect.
[0082] The mister 106 can provide the instant cooling effect. For
example, when the evaporative air cooler 10 is powered ON, the mist
118 begins spraying from a mister 106. The power of the fan 48 can
be positioned behind the mist 118 to distribute the mist 118 into
the ambient air, or air, and onto the filters 58. As the mister 106
runs for a continued period of time, the filters 58 may become more
wet (e.g., damp filters). The air that encounters the mist 118 can
feel cooler to the user due to the evaporative cooling process. As
air continually travels through the damp filter 58, the cooling
effect can be prolonged. When the liquid is depleted from the water
tank 40, the mist 118 may cease but the filters 58 can remain wet
for a time period, allowing at least some evaporative cooling to
continue.
[0083] The misting structure 104 can be located or partially
located within the water tank 40. For example, the mister 106 can
be assembled through the aperture 42 of the water tank 40. The
misting structure 104 can be coupled to the bottom of the water
tank 40, the top internal panel 110, or any other desirable
location using a misting structure coupling 126. The misting
structure coupling 126 can include a screw inserted through a screw
hole, or any other desirable attachment. The mister 106 can be
positioned upside down within the top-filled water tank 40. The
mister 106 can release the liquid downward into the interior of the
evaporative air cooler 10. Liquid can be fed directly into the
mister 106. The mister 106 can distribute mist 118 (e.g., moisture)
to the sponge filter. By misting the filters 58 from an upper
portion of the evaporative air cooler 10, the mist 118 can more
effectively soak into the filters 58. The mister 106 can create an
even distribution of the mist 118 to the filters 58, including to a
top portion 112 of the filters 58. Walls of the water tank 40 can
have angles configured to allow for an increased volume of liquid
to reach the mister 106.
[0084] The mister 106 can be configured to restrict water flow from
the aperture 42 when the evaporative air cooler 10 is turned
OFF.
[0085] The misting structure 104 can be wired to the evaporative
air cooler 10. The wires can be soldered to electrically connect
the misting structure 104 to the evaporative air cooler 10, or
attached in any other desirable way. The wires can be hidden in the
wire compartment or any other desirable compartment within the
evaporative air cooler 10.
[0086] The evaporative air cooler 10 can operate for a period of
time. The period of time may depend on various factors, such as the
amount of water in the water tank 40, whether the filter 58 are
presoaked, whether the filters 58 were initially frozen, and a
cooling mode selected based on the fan speed. In one embodiment,
the evaporative air cooler 10 can operate for eight hours on the
high mode, ten hours on the medium mode, and twelve hours on the
low mode without refilling the water tank 40.
[0087] The evaporative air cooler 10 can include additional and/or
fewer components and is not limited to those illustrated in the
figures.
[0088] In an example embodiment, the evaporative air cooler 10
includes the water tank 40, the misting structure 104, the filter
structure 56, and the fan 48. The water tank 40 can include the
liquid inlet (e.g., via the hinged lid 32) and the liquid outlet
(e.g., via the aperture 42). Liquid can enter the water tank 40
through the liquid inlet and exit the water tank through the liquid
outlet. The misting structure 104 can be in liquid communication
with the water tank 40. The misting structure 104 can be configured
to produce mist 118 as the liquid flows through the liquid outlet.
The filter structure 56 can include the plurality of filters 58
positioned substantially parallel to each other and defining air
gaps 92 between the plurality of filters 58. The fan 48 can be
configured to draw ambient air into the evaporative air cooler 10
and direct the ambient air through the filter structure and out of
the evaporative air cooler 10. Thus, the ambient air can be cooled
before exiting the evaporative air cooler 10.
[0089] The misting structure 104 can distribute the mist 118 into
the ambient air and onto the plurality of filters 58. The misting
structure 104 can include a mister 106. The mister 106 can be
positioned adjacent the water tank 40. The mister 106 can also be
positioned within the water tank 40. Liquid can flow through a top
portion of the mister 106 from the water tank 40 toward a bottom
portion of the mister 106. The mister 106 can project the mist 118
from the misting structure 104 into the ambient air within the
evaporative air cooler 10. The mist 118 can cool the ambient
air.
[0090] The misting structure 104 can produce a first volume of mist
118 when the fan 48 is at a first speed. The misting structure 104
can produce a second volume of mist 118 when the fan is at a second
speed. The first volume can be larger than the second volume and
the first speed can be faster than the second speed. In other
words, when the fan is on high, more mist 118 can spray from the
mister 106.
[0091] The evaporative air cooler 10 can include an internal
assembly 74 configured to form a seal 116 with the fan 48. The seal
116 can cause the ambient air to exit the evaporative air cooler 10
with a greater force than when entering the evaporative air cooler
10. The internal assembly 74 can include at least one of the filter
structure 56, and a drawer 50. The internal assembly 74 can be
removably attached to the evaporative air cooler 10. The internal
assembly 74 can comprises a drawer 50 attached to the outlet vent
52. The drawer 50 can include a water tray 54 angled toward the
outlet vent 52. The filter structure 56 can be positioned on the
water tray 54 adjacent the outlet vent 52. Any condensation or
liquid in the drawer 50 can flow toward the outlet vent 52. The
plurality of filters 58 can be formed from sponge-like material,
such as sponge material 60. Thus, if the filter structure 56 is
positioned adjacent the outlet vent 52, the plurality of filters 58
can soak up the liquid as it flows toward the outlet vent 52. If
the plurality of filters 58 are at a liquid capacity, the sponge
material 60 may not soak up additional liquid. The liquid in the
filters 58 can be used to cool the ambient air. When the liquid in
the filters 58 cools the ambient air, the liquid may evaporate from
the filters 58. The filters 58 may not be at the liquid capacity
after evaporation occurs and thus, can soak up more liquid.
[0092] The filter structure 56 can be configured for removal from
the evaporative air cooler 10. The filter structure 56 and the
plurality of filters 58 can be washable and reusable. The plurality
of filters 58 can be presoaked with liquid and inserted into the
evaporative air cooler 10. Presoaking the filters 58 can prolong
the cooling of the evaporative air cooler 10.
[0093] The evaporative air cooler 10 can include a shroud, such as
the v-shaped shroud 44, adjacent to the underside of the water tank
40. The shroud can be v-shaped or any other desirable shape.
[0094] In an example embodiment, the portable evaporative air
cooler 10 for cooling ambient air includes the misting structure
104, the filter structure 56, and the fan 48. The misting structure
104 can be configured to evaporate liquid within the portable
evaporative air cooler 10. The filter structure 56 can include the
plurality of filters 58 configured to absorb liquid. The fan 48 can
be configured to draw the ambient air into the portable evaporative
air cooler 10. The ambient air can be cooled by at least one of the
mist 118 and the filter structure 56. The fan 48 can direct the
ambient air thorough the filter structure 56 and out of the
portable evaporative air cooler 10.
[0095] The plurality of filters 58 can be formed from a sponge
material 60 and positioned to define gaps, such as air gaps 92,
between the plurality of filters 58. The plurality of filters 58
can be removable from the portable evaporative air cooler 10. The
plurality of filters 58 can be soaked with liquid prior to entering
the portable evaporative air cooler 10.
[0096] The filter structure 56 can be positioned in a drawer 50.
The drawer 50 can be removable from the portable evaporative air
cooler 10. The portable evaporative air cooler 10 can include a
front grill, such as the outlet vent 52, with the air direction tab
72 for directing air flow and the filter drawer tab 120 for pulling
the drawer 50 from the portable evaporative air cooler 10.
[0097] In an example embodiment, the personal air cooler 10
comprises the housing 20, the tank, such as the water tank 40, the
misting structure 104, the filter structure 56, and the v-shaped
shroud 44. The housing includes a top panel (e.g., the top face
22), a bottom panel (e.g., the bottom face 24), and side panels
(e.g., the front face 26, the back face 28, and the side faces 30)
that can define an interior of the personal air cooler 10. The tank
can be positioned adjacent the top panel and at least one of the
side panels and configured to receive, store, and release liquid.
The misting structure 104 can be in fluid communication with the
tank and configured to create the mist 118. The filter structure 56
can be adjacent the bottom panel and at least one of the side
panels. The v-shaped shroud 44 can be positioned underneath the
tank and configured to direct the mist 118 toward the filter
structure 56.
[0098] The personal air cooler 10 can include the fan 48 positioned
adjacent one of the side panels. The personal air cooler 10 can
also include a fan cover 46 adjacent the fan 48 and configured to
direct air from outside the personal air cooler 10 toward the
v-shaped shroud 44. The v-shaped shroud 44 can direct mist 118
toward a top portion of the filter structure 56 and through the
filter structure 56.
[0099] The filter structure 56 can include a plurality of filters
58 positioned substantially parallel to each other. Each of the
plurality of filters 58 can be spaced apart a specific distance,
such as 1 cm, or any other desirable distance. Thus, the plurality
of filters 58 can define a plurality of air gaps 92. The plurality
of filters 58 can store the mist 118. The air can be cooled by the
mist 118. The cooled air can travels through the air gaps 92 and
exit the personal air cooler through one of the side panels. The
side panel can be the side panel adjacent the filter structure 56
and include the outlet vent 52.
[0100] FIGS. 10-19 illustrate an evaporative air cooler 200 for
cooling air. The evaporative air cooler 200 can include the housing
220 with a top face 222, a bottom face 224, and four lateral faces,
such as a front face 226, a back face 228, and side faces 230. The
housing 220 may be formed in the shape of a cube, a cuboid, a half
sphere, or any other suitable shape. The housing 220 may be formed
from plastic or any other desirable material.
[0101] The top face 222 can include a lid, such as a lid 232. FIGS.
12 and 13 illustrate the evaporative air cooler 200 with the lid
232 opened for access to the tank 240. The lid 232 can be located
along a front portion of the top face 222. The lid 232 can include
a lid tab 276 formed as a back portion of the lid 232 or any other
desirable location. The lid 232 can be opened to allow for water to
fill the tank 240. For example, a user can pull the lid tab 276
upward to open the lid 232. The lid 232 can be formed from plastic
or any other desirable material. A tank opening 244 to the tank 240
can be any desirable opening. When in a closed position, the lid
232 can be configured to form a seal over the tank opening 244. The
lid 232 and the tank opening 244 may be ovular or any other
suitable shape or configuration.
[0102] The front face 226 can also include buttons, such as a power
button 234 or any other desirable button. The power button 234 can
be configured to activate (e.g., power ON), change the fan speed of
the fan 248, and deactivate (e.g., power OFF) the evaporative air
cooler 200. For example, when the power button 234 is first
activated, an indicator light 238 can turn ON, the fan 248 can turn
ON (e.g., to a high speed), and an aperture 242 positioned in the
tank 240 can allow water to flow out of the tank 240 to begin the
evaporative air cooling process. When the power button 234 is
activated a second time, the fan speed can decrease (e.g., to a
medium speed) and the aperture 242 can allow less water to flow out
of the tank 240. When the power button 234 is activated a third
time the fan speed can decrease (e.g., to a low speed) and the
aperture 242 can allow less water to flow out of the tank 240. When
the power button 234 is activated a fourth time, the indicator
light 238 can turn OFF (e.g., no indicator lights 238 remain ON),
the fan 248 can turn OFF, and the aperture 242 can stop the water
from flowing out of the tank 240. In other words, the power button
234 can be activated to deactivate, or power OFF the evaporative
air cooler 200. In one embodiment, when the power button 234 is
activated (e.g. depressed) for three or more seconds, it can turn
OFF the indicator light 238 and the evaporative air cooler 200.
[0103] The front face 226 can be configured to emit one or more
lights, such as an indicator light 238 or any other desirable light
or indicator. The front face 226 may include a semi-transparent
section, such as a window 250. The indicator light 238 may comprise
one or more lights, such as a blue LED light, positioned within the
tank 240, or any other desirable area for illuminating the tank 240
and/or the window 250. The light can be used for ambiance, such as
for a nightlight, to indicate fan speed, to indicate that the
evaporative air cooler 200 is ON, or any other desirable purpose.
The light may be on by default when the evaporative air cooler 200
is powered ON. The brightness of the indicator light 238 may be
configured to change. For example, after the power button 234 is
pressed, the light may be on a high brightness mode. When the user
presses the power button 234 for a second time, the light can
reduce its brightness (e.g., to a medium brightness mode). When the
user presses the light button for a third time, the light can
reduce its brightness (e.g., to a low brightness mode). When the
user presses the power button 234 for a fourth time, the indicator
light 238 can turn OFF. In one embodiment, if the power button 234
is activated for a minimum amount of time (e.g., three seconds), an
illumination setting can be selected and/or locked.
[0104] The power indicator light 236 may be used to indicate a that
the evaporative air cooler 200 is low on battery, charging, or
fully charged; whether the filter 258 should be replaced; or any
other desirable indication. The power indicator light 236 may
display a blinking light or a solid light. The power indicator
light 236 may display different light colors, such as green, red,
amber, or any other desirable color.
[0105] The evaporative air cooler 200 can include the housing 220.
The housing 220 can define an interior 254 of the evaporative air
cooler 200. The interior 254 can be configured to receive a filter

center portion of the filter structure 256. The tabs 372 can be
configured to direct the mist 118, water, and the like toward the
back of the filter structure 256. When the filter structure 256 is
within the interior 254 of the evaporative air cooler 200, the tabs
372 can direct the water, the mist 118, and the like toward the fan
248.
[0106] The filter structure 256 can comprise one or more filters,
such as filters 258, 262. The filter 258 can be positioned through
one of the bottom openings 340 from one side of one of the bottom
bars 338 to other side of that bottom bar 338. The filter 258 can
be positioned around the top portion of one of one of the top bars
368. When the upper and lower top walls 342, 344 are in a locked
position, the filter 258 and the top bars 368 are positioned within
the slits 370. The filter 258 can include this configuration for
each of the bars 338, 368 to form a zig-zag configuration of the
filter 258. Each of the ends of the filter 258 can couple to one of
the side walls 332, the bottom wall 330, or any other suitable
component. For example, the side walls 332 can include hooks 364
and each of the ends of the filter 258 can include an opening
configured for insertion of one of the hooks 364.
[0107] The filter structure 256 can include a filter holder 284.
The filter holder 284 can be coupled to the filter frame 282. For
example, the filter holder 284 can be snapped to each of the side
walls 332 of the filter frame 282. The filter holder 284 can be
coupled to the filter frame 282 at a middle portion of each of the
side walls 332. The filter structure 256 can be configured for

348 of the filter structure 256. The pull tab 272 can be configured
for a user to pull the pull tab 272 to remove the filter structure
256 from the interior 254 of the housing 220 and/or to insert the
filter structure 256 into the interior 254. In this example, the
user can remove a grill 252 from the housing 220 and pull the pull
tab 272 to remove the filter structure 256. The filter structure
256, including the filters 258, 262 can be reusable. The filter
structure 256 and the filters 258, 262 can be washed. The filter
structure 256 and the filters 258, 262 can be replaced.
[0108] The interior 254 can include filter structure stoppers 308.
The filters structure stoppers 308 can be coupled or formed into
interior portions of the side faces 230 and/or the back face 228.
The filter structure stoppers 308 can be formed from plastic or any
other desired material. The filter structure stoppers 308 can be
configured to position the filter structure 256 into a desired
position within the interior 254. In other words, the filter
structure stoppers 308 stop and/or generally hold the filter
structure stoppers 308 into place adjacent to, but not touching the
fan 248. As illustrated in FIGS. 15 and 16A-C, the filter structure
256 can comprise filter structure stopper tabs 310 coupled to or
formed into the front side portions of the filter structure 256.
The filter structure stopper tabs 310 can be formed from plastic or
any other desired material. The filter structure stopper tabs 310
can be configured to position the filter structure 256 into a
desired position within the interior 254. In other words, the
filter structure stopper tabs 310 stop and/or generally hold the
filter structure stoppers 308 into place adjacent to, but not
touching the fan 248.
[0109] The filter holders 284 can include bars 296 that define
openings, such as slits 298. The bars 296 of the filter holders 284
extend from one side of the filter holder 284 to the opposing side
of the filter holder 284. The filter 258 can be positioned through
each of the filter holders 284. The filter holder 284 can provide
additional support for securing the filter 258 to the filter frame
282. The filter holder 284 can further assist in maintaining the
configuration of the filter 258 in the zig-zag formation when the
filter 258 is dry, damp, wet, or a combination thereof.
[0110] A second filter 262 can be coupled to at least a portion of
a perimeter 302 of the filter structure 256. In one embodiment, the
second filter 262 is positioned adjacent the outer perimeter 302 of
the top wall 334 and the side walls 332. Each of the ends of the
second filter 262 can be coupled to the a bottom portion of each of
the side walls 332. For example, the side walls 332 can include
hooks 364 and each of the ends of the second filter 262 can include
an opening configured for insertion of one of the hooks 364. The
second filter 262 can be configured to absorb the mist 118. The
second filter 262 can be formed from the same material as the
filter 258, such as the sponge material 260, or any other suitable
material. The second filter 262 can be in fluid communication with
the filter 258. The filter 258 can absorb the liquid and/or mist
118 absorbed by the second filter 262. For example, portions of the
filter 258 can be positioned through the top wall 334 of the filter
structure 256 and are adjacent to the second filter 262 positioned
adjacent to the top wall 334 (e.g., along the perimeter 302 of a
portion of the filter frame 282). The filters 258, 262 may be
touching or in close proximity to each other. The second filter 262
can be coupled to the two side walls 332, the bottom wall 330, any
other suitable wall, or combination thereof. In one embodiment, the
filters 258, 262 are the same filter. In another embodiment, the
second filter 262 is not included in the filter structure 256.
[0111] The filter 258 can be configured in a zig-zag formation and
define air gaps 292. The filter 258 can be configured to store
liquid, such as mist 118, water, any other suitable liquid, or
combination thereof. The filter is configured to absorb the mist
118 from the mister, absorb liquid from being pre-soaked, store
liquid via being frozen, or any other suitable means to absorb or
store liquid. The air gaps 292 are configured to allow for air to
flow through the filter structure 256, contact the filters 258, 262
to cool the air, and exit the interior 254.
[0112] The filter structure 256 can include a fan cover 246. The
fan cover 246 can be coupled to a back side 278 of the filter
structure 256. The fan cover 246 can be positioned adjacent the
fan. The fan cover 246 can be configured to direct air from the fan
toward the filter structure 256. The fan cover 246 can be
configured to form a suction with the fan, such as to provide
additional force in directing the air from outside of the housing
220 through the fan cover 246, the filter structure 256, and the
grill 252. In this way, the fan cover 246 can be configured to
direct air flow through the interior 254 of the evaporative air
cooler 200.
[0113] The fan 248 can be positioned adjacent one of the sides of
the housing 220, such as the back face 228. The fan 248 can be
configured to draw the air into the evaporative air cooler 200,
such as through grate openings 300 in the back face 228 of the
housing 220. The air can be cooled by at least one of the mist 118
and the filters 258, 262. The fan 248 can include blades 264. The
fan 248 may include four blades 264 or any other suitable number of
blades. The fan 248 may include a motor 266. The motor 266 can be
used to control the fan 248 to rotate the blades 264. The motor 266
can rotate the blades 264 at various speeds. The speed of rotation
of the blades 264 can change the amount (e.g., volume) of air and
the speed for which the air flows through the filter structure 256
and out of the interior 254 of the evaporative air cooler 200. The
evaporative air cooler 200 can include different levels of speed,
each of which can be configured to direct air. A higher level may
direct a larger amount of air at a first speed. A mid-range level
may direct a mid-range amount of air at a second speed. A lower
level may direct a lower amount of air at a third speed. The first
speed may be greater than the second speed. The second speed may be
greater than the third speed. The evaporative air cooler 200 can be
configured to have predefined speeds, a variable speed, or any
combination thereof.
[0114] The fan 248 can be wired to the evaporative air cooler 200.
The wire 322 can be soldered to electrically connect the fan 248 to
the evaporative air cooler 200, or attached in any other desirable
way. The wire 322 can be hidden in a wire compartment or any other
desirable compartment within the evaporative air cooler 200.
[0115] As illustrated in FIG. 18, the back face 228 can include a
grate 294 defining grate openings 300. The grate openings 300 can
be configured throughout the grate 294. The grate 294 can be a
portion of the back face 228, such as a central portion of the back
face 228. The grate 294 can be a rectangle, a square, a circle, an
oval, or any other suitable shape. The grate openings 300 can
include one or more shapes (e.g., circular, rectangular, ovular,
any other suitable shape, or combination thereof). Air, such as
ambient air, can enter from outside of the housing 220 through the
grate openings 300 of the grate 294 and into the interior 254 of
the evaporative air cooler 200. The grate 294 may be configured to
protrude from the back face 228. The fan 248 can be coupled to the
back face 228. More specifically, the grate 294 may include a fan
coupling 288 to couple to the fan 248. The protrusion of the grate
294 from the back face 228 can be configured for housing the fan
248.
[0116] The evaporative air cooler 200 can be powered by a power
source, such as a battery or any other suitable power source. The
battery can be a rechargeable battery, such as a Lithium-ion
battery (LIB) or any other rechargeable power source. The
evaporative air cooler 200 can include a charging port (not shown)
to charge the rechargeable battery. The charging port can be
disposed on the back face 228 or any other desirable location on
the evaporative air cooler 200. The charging port (not shown) can
be configured to receive the charger 268. The evaporative air
cooler 200 can operate using a rechargeable battery and/or when
plugged into an electrical outlet.
[0117] As illustrated in FIGS. 14 and 17, the front face 226 of the
housing 220 may define an opening, such as a front opening 286. The
grill 252 can be coupled to the front face 226 to cover the front
opening 286. The grill 252 may include grill tabs 274 configured to
secure the grill 252 to the housing 220. The grill tabs 274 may be
couple to or formed into the grill 252. The grill tabs 274 may be
positioned in each of the corners of the grill 252. The grill 252
can be configured to removably couple to the front face 226 of the
housing 220. Each of the grill tabs 274 can be inserted into one of
the openings 324 in the housing 220. The openings 324 can be
located in the bottom face 224, the front face 226, or any other
desired location in the housing 220. When coupled to the housing
220, the grill 252 can provide a front side to the housing 220. The
grill 252 can include vents 270 (e.g., bars). The vents 270 may be
configured in a horizontal configuration, an angled configuration,
any other suitable configuration, or combination thereof. The vents
270 may be stationary. The vents 270 can be configured to rotate.
Each of the vents 270 may be aligned parallel to one another such
that the vents 270 are configured to allow for air to pass through
the vents 270.
[0118] The evaporative air cooler 200 can include an angling member
210. The angling member can be coupled to the housing 220. The
angling member can include arms 352, 354 and a base 356. A first
arm can be rotatably coupled to one of the side faces 230 of the
housing 220. A second arm 354 can be rotatably coupled to the
opposing side face 230. In one embodiment, the first and second
arms 352, 354 couple to a center portion of the side faces 230. The
arms may be coupled to the sides via a coupling 358, such as a
ratchet system or any other desired rotatable attachment. The
angling member can be configured to rotate the housing 220. The
angling member can rotate the housing 220 to position the housing
220 in an angle that a user desires. The angling member can be
configured to rotate the housing 220 in a vertical direction. The
angling member 210 can be configured to rotate the housing 220 360
degrees. The angling member 210 can maintain a position, or angle,
of the housing 220 relative to the angling member 210. For example,
if a user would like the evaporative air cooler 200 to blow cool
air toward the user's face, the user may rotate the housing 220
upward to direct the cooled air upward. Similarly, the user can
rotate the housing 220 downward to direct the cooled air downward.
The arms 352, 354 can be coupled to the sides such that the housing
220 is stationary and cannot be rotated about the arms.
[0119] The first and second arms 352, 354 can protrude from either
side of the base 356. The first and second arms 352, 354 can be
formed with the base 356 or coupled to the base 356. The base 356
can be formed from plastic or any other suitable material. The base
356 can be coupled to a clip 202 via a coupling 360, such as a
ratchet system or any other desired rotatable attachment. The
coupling 360 can be configured to rotate housing 220 via the base
356 in either direction (e.g., to the right or to the left) 360
degrees or any other desirable degree rotation.
[0120] The evaporative air cooler 200 can include a fastener, such
as the clip 202. The clip 202 can be a device that is rotatable or
worked by a spring 380 for holding an object or objects together or
in place. For example, the clip 202 can be configured to removably
couple the evaporative air cooler 200 to the handle 206 of the
stroller 204, the countertop 208, a desk, a table, or any other
suitable object. The clip 202 may include grips 382, 384 on one or
more components of the clip 202. For example, the grip 382 may be
configured on a grip side 388 of the clip 202 and the grip 384 may
be configured on a grip side 390 of a clip base 376. The grips 382,
384 can be configured to more securely attach the evaporative air
cooler 200 to the object. The grips 382, 384 can be formed from
rubber, plastic, or any other desired material. The grips 382, 384
may be formed as ridges and/or a smooth surface. The smooth surface
may be configured to protect the object to which the clip 202
attaches to, such that the clip 202 does not damage (e.g., scrape,
scratch, etc.) the object.
[0121] The clip 202 can be coupled to the clip base 376 via a
coupling 392. The coupling 392 can comprise a rod 386 configured
for insertion into rod holders 394, 396. The rod holders 394 can be
coupled to or formed at the end of one of the sides of the clip.
The rod holders 396 can be coupled to or formed on the grip side
390 of the base. Each of the rod holders 394, 394 can define an
opening for the rod 386 to insert through. A spring 380 can define
an opening be configured for the rod 386 to insert through. The
spring 380 can provide tension to the clip 202 relative to the clip
base 376. In a closed position, the clip 202 may be configured such
that one end of the clip 202 (e.g., a grip end 398) extends further
than the clip base 376. The grip end 398 is configured for a user
to rotate the clip 202 by exerting force on the grip end 398 to
rotate the clip 202 about the coupling 392. The user can open the
clip 202 for an object to be inserted into the clip 202. When the
user releases the clip 202, the tension provided by the spring 380
couples the clip 202 to the object and secures the evaporative air
cooler 200 into the desired place.
[0122] The clip 202 can include one or more support members 400.
The one or more support members 400 can be configured on opposing
sides of the clip 202, along the clip 202, or any other desired
position. The one or more support members 400 can be configured to
support the evaporative air cooler 200 in an upright position when
the clip 202 is in a closed position. In other words, the one or
more support members 400 support the evaporative air cooler 200 so
that the evaporative air cooler 200 does not easily tip over when
it is placed on a surface. Similarly, the clip base 376 may
comprise a front face 378 configured to provide support for the
evaporative air cooler 200 when the evaporative air cooler 200 is
placed on a surface (e.g., with the clip in the closed position).
The front face 378 may protect components of the coupling 392 from
being damaged. For example, the front face 378 can stop the clip
202 from being rotated too far such that the spring 380 is
overextended.
[0123] The clip 202 can be coupled to the angling member 210.
Specifically, the clip base 376 can be coupled to the base 356 of
the angling member. 210 The clip base 376 can be rotatably coupled
to the base 356, such as to a bottom portion of the base 356. The
clip base 376 may be coupled to the base 356 via the coupling 360,
such as a ratchet system or any other desired rotatable attachment.
The base 356 can be configured to rotate the housing 220 about the
clip base 376 in a horizontal direction. The base 356 can rotate
about the clip base 376 in either direction horizontally 0-360
degrees. For example, a user can attach the evaporative air cooler
200, via the clip 202, to the countertop 208. The user can rotate
the housing 220 of the evaporative air cooler 200 horizontally, via
the base 356, toward the user. The user can further rotate the
housing 220 vertically, via the angling member 210, toward the
user. In this way, when the evaporative air cooler 200 is turned
on, the cooled air can be directed toward the user. In another
embodiment, the housing 220 can be coupled to the angling member
210 and the base 356 can be coupled to the clip base 376 such that
the housing 220 is stationary and cannot be rotated in horizontal
and/or vertical directions.
[0124] As illustrated in FIGS. 13 and 14, the evaporative air
cooler 200 can include a tank 240. The tank 240 can be positioned
adjacent to a top face 222 of the housing 220. Portions of the
interior of the top face 222, the front face 226, the back face
228, and the side faces 230 of the housing 220 may form portions of
the tank 240. For example, the tank 240 can be configured within
the housing 220 such that the top portion of the tank 240 is an
underside of the top face 222 of the housing 220. The tank 240 can
include a front side and a bottom side coupled to the housing 220.
The front side and the bottom side of the tank 240 may comprise the
window 250. A light, such as the power indicator 236 can be
disposed adjacent to the bottom side of the tank 240, or any other
desired location. The bottom side of the tank 240 and the front
portion of the tank 240 may comprise the window 250 and be
configured to emit light produced by the power indicator 236
throughout the tank 240. The power indicator 236 may also be
configured to emit light into the interior 254 and toward the
outside of the evaporative air cooler 200.
[0125] The tank 240 can include a liquid inlet 312 and a liquid
outlet 314. The top portion of the housing 220 can define an
opening, such as liquid inlet 312. The liquid inlet 312 can be
ovular, circular, or any other desirable shape. The bottom portion
of the tank 240 can define an opening, such as the liquid outlet
314. The liquid outlet can be ovular, circular, or any other
desirable shape. The liquid outlet 314 can be positioned in the
bottom of the tank 240. The liquid outlet 314 can be positioned in
a central location in the bottom of the tank 240. The liquid outlet
can be positioned adjacent a filter structure 256. The liquid
outlet 314 can be configured to receive a misting structure 304
comprising a mister 306. Liquid, such as water, can enter the tank
240 through the liquid inlet 312 and exit the tank 240 through the
liquid outlet 312. In response to the liquid flowing through the
liquid outlet 314, the mister 306 can be configured to create, from
the liquid, a mist in the interior 254 of the evaporative air
cooler 200.
[0126] As illustrated in FIGS. 12 and 13, a lid 232 can be coupled
to the top face 222, or any other suitable portion of the housing
220. The lid 232 can be coupled to the top face 222 via a hinge, a
cord, or any other suitable attachment. A portion of the lid 232
can be configured to fit within the liquid inlet 312. For example,
if the liquid inlet 312 is an oval shape, the lid 232 can be a
slightly smaller oval shape so as to fit within the liquid inlet
312 and form a seal 316 when the lid 232 is in a closed position.
The lid 232 may include an ovular seal 316 to form a seal with the
liquid inlet 312 such that liquid remains in the tank 240. The lid
232 may be formed from plastic or any other desirable material. The
seal 316 may be formed from rubber or any other desirable material.
The tank 240 can be configured to receive, store, and release
liquid. For example, when the lid 232 is open (see FIG. 13), liquid
can be poured into the tank 240 using a pitcher, a faucet, a water
bottle, or any other desirable filling means.
[0127] The mister 306 can be positioned adjacent the tank 240. The
mister 306 can be coupled to the liquid outlet 314. The mister 306
can be in fluid communication with the tank 240. Liquid can flow
through a top portion of the mister 306 from the tank 240 toward a
bottom portion of the mister 306. The mister 306 can be configured
to create the mist 118 from the liquid stored in the tank 240. The
mister 306 can distribute the mist 118 into the air into the
interior 254 of the evaporative air cooler 200 and onto a filter,
such as the second filter 262. The mist 118 can cool the air within
the interior 254.
[0128] When the evaporative air cooler 200 is operating, the mister
306 can produce mist 118. For example, the mister 306 can be
configured to create a first volume of mist 118 when a fan 248 is
at a first speed. The mister 306 can be configured to create a
second volume of mist 118 when the fan 248 is at a second speed
(the aperture 242 of the misting structure 304 can allow less water
to flow out of the tank 240). The mister 306 can be configured to
create a third volume of mist 118 when the fan 248 is at a third
speed. The first volume can be greater than the second volume and
the first speed can be faster than the second speed. In other
words, when the fan 248 is on high, a higher volume of mist 118 can
spray from the mister 306. Similarly, the first and second volumes
can be greater than the third volume and the first and second
speeds can be faster than the third speed. The evaporative air
cooler 200 can have a button, such as the power button 234, for
controlling the speed of the fan 248. For example, when the power
button 234 is engaged a first time, the fan 248 can operate at the
first speed. When the power button 234 is engaged for a second
time, the fan 248 can operate at the second speed. When the power
button 234 is engaged for a third time, the fan 248 can operate at
the third speed. When the power button 234 is engaged for a fourth
time, the fan 248 can turn off (i.e., to end operation of the fan
248). The evaporative air cooler 200 may have any number of speeds
and is not limited to those described in this disclosure. The
evaporative air cooler 200 can have a light (e.g., the power
indicator 236), such as an LED light or any other desired light, to
indicate that the evaporative air cooler 200 is operating. The
power indicator 236 can be configured to indicate the speed of
operation.
[0129] The evaporative air cooler 200 can include a safety
interlock 320. The safety interlock 320 can be configured to
prevent operation of the evaporative air cooler 200. For example,
if at least one of the grill 252 and the filter structure 256 is
removed from the housing 220, the safety interlock 320 can shut off
operation of the evaporative air cooler 200. The safety interlock
320 can function as a safety feature such that a user does not
touch the blades of the fan while the fan is spinning in
operation.

a filter 524 configured to receive the liquid from the tray 514.
The evaporative air cooling tower 500 can include a fan 528
configured to draw air into the interior 504. The air can be cooled
by the filter 524 and directed out of the interior 504 through the
openings 508. In some embodiments, the tray 514 is a filter tray
570 and the hose 518 is in fluid communication with the filter tray
570.
[0133] As generally illustrated in FIG. 23, the grill 506 may be
substantially rectangular in shape, or any other desired shape. The
grill 506 may be formed of plastic or any other suitable material.
The grill 506 may include a plurality of openings positioned
adjacent to one or more openings. The openings 508 may be
rectangular in shape, any other shape, or combination thereof. The
grill 506 may define one or more sets of openings 508. The sets of
openings 508 may include a plurality of openings 508 that are
substantially rectangular openings of about the same size, each of
which are positioned adjacent to one or two openings 508 of the set
of openings 508. The set of openings 508 can be positioned between
two sides of the grill 506. Each of the plurality of the sets of
openings 508 may be positioned adjacent to one or two of the sets
of openings 508. In some embodiments, the grill 506 may include six
sets of openings 508, each of which includes seven openings 508.
The quantity of sets of openings 508 and the opening 508, may
include additional and/or fewer sets of openings 508 and/or
openings 508 and are not limited to the examples in this
disclosure. The openings 508 may comprise different sizes and
shapes from other openings 508. The grill 506 may be configured to
removably couple to the housing 502. The openings 508 can be
configured for air to flow through. For example, when the
evaporative air cooling tower 500 is turned on, the fan 528 can
direct air from the interior 504 out of the evaporative air cooling
tower 500 through one or more of the openings 508. The grill 506
may include fixed vent or a directional vent. The positions of the

which are positioned adjacent to one or two fixed grill openings
536 of the set of fixed grill openings 536. The set of fixed grill
openings 536 can be positioned between two sides of the fixed grill
534. Each of the plurality of the sets of fixed grill openings 536
may be positioned adjacent to one or two of the sets of fixed grill
openings 536. In some embodiments, the fixed grill 534 may include
forty-eight sets of fixed grill openings 536, each of which
includes three fixed grill openings 536. The quantity of sets of
fixed grill openings 536 and the opening 508, may include
additional and/or fewer sets of fixed grill openings 536 and/or
fixed grill openings 536 and are not limited to the examples in
this disclosure. The fixed grill openings 536 may comprise
different sizes and shapes from other fixed grill openings 536. The
fixed grill openings 536 can be configured for air to flow through.
For example, when the evaporative air cooling tower 500 is turned
on, the fan 528 can direct air from outside of the housing 502 into
the interior 504 of the evaporative air cooling tower 500 through
one or more of the fixed grill openings 536.
[0136] The evaporative air cooling tower 500 can include the
housing 220. The housing 220 can define an interior 504 of the
evaporative air cooling tower 500. As generally illustrated in FIG.
24, the interior 504 can be configured to receive the filter
structure 522. As generally illustrated in FIG. 25A, the filter
structure 522 can comprise a filter frame 546. The filter frame 546
may be formed from plastic or any other suitable material. The
filter frame 546 may be formed in a rectangular shape or any other
suitable shape. The filter structure 522 via the filter frame 546
may comprise a bottom wall 548, two side walls 550, and a top wall
552. As generally illustrated in FIG. 25B, the bottom wall 548 can
define openings and include bottom bars 556 positioned within the
openings to define bottom slits 558. The bottom wall 548 can be
configured for the filter 524 to be received through one of the
bottom slits 558, around side and bottom portions of an adjacent
bottom bar 556 and through an adjacent bottom slit 558. As
generally illustrated in FIG. 25E, the top wall 552 can define
openings and include top bars 560 positioned within the openings to
define top slits 562. The top wall 552 can be configured for the
filter 524 to be received through one of the top slits 562, around
side and bottom portions of an adjacent top bar 560 and through an
adjacent top slit 562. The bottom wall 548 and the top wall 552 can
be configured such that a first bottom slit 558 substantially
aligns with a first top slit 562, a second bottom slit 558
substantially aligns with a second top slit 562, and so forth such
that the filter 524 can be received by each of the bottom and top
slits 558, 562. The filter 524 may be a single filter that loops
around the bottom and top bars 556, 560. Each of the ends of the
filter 524 can couple to the filter structure 522. For example,
each of the ends of the filter 524 can couple to the side walls
550, the top wall 552, the bottom wall 548, any other suitable
portion of the filter structure 522, or combination thereof. The
filter 524 may be configured within the filter structure 522 in a
coil shape, an "s" shape, or any other desired shape or
configuration. In some embodiments, the filter 524 comprises more
than one filter configured to couple to and/or be secured by bottom
and top walls 548, 552. The filter 524 can be coupled to the filter
structure 522 using an adhesive, such as glue, tabs, snaps, or any
other desired coupling.
[0137] As generally illustrated in FIGS. 25A and 25E, the filter
structure 522 can comprise one or more filter holders 544. The
filter holders 544 can be positioned between the two sides (e.g.,
side walls 550) of the filter structure 522. The filter holders 544
may be coupled to the side walls 550 via filter holder couplings
568. For example, one end of the filter holder 544 may be coupled
to one of the side walls 550 at a first filter holder coupling 568.
An opposing end of the filter holder 544 may be coupled to an
opposing side wall 550 at a second filter holder coupling 568. The
filter holders 544 may define filter holder slits 566. The filter
holder slits 566 can define a rectangular opening adjacent to two
circular openings. The filter holder slits 566 may define openings
in any desired shape or combination of shapes. The filter holder
slits 566 can be configured to receive the filter 524. The filter
holder slits 566 can be configured to secure a portion of the
filter 524 in a place. The filter holder 544 may include a
plurality of filter holder slits 566. The filter holder slits 566
may align substantially vertically with filter holder slits 566
defined by other filter holders 544 coupled to the filter frame
546. In some embodiments, the filter structure 522 comprises five
filter holders 544, each comprising six filter holder slits 566.
The filter 524 can be received through each of the filter holder
slits 566, such that the filter 524 is received through
substantially aligned filter holder slits 566 in a first direction
through the first filter holder slits 566 of each of the filter
holders 544, received through substantially aligned filter holder
slits 566 in a second direction through the second filter holder
slits 566 of each of the filter holders 544, received through
substantially aligned filter holder slits 566 in the first
direction through the third filter holder slits 566 of each of the
filter holders 544, and so forth until the filter is received
through each of the filter holder slits 566. In this configuration,
the filter 524 is positioned in columns between the two side walls
550 of the filter structure 522. The filter holders 544 may define
slits (e.g., filter holder slits 566) for receiving the filter 524,
such that the filter holder slits 566 are positioned between 5-85
degrees relative to at least one of the two sides (e.g., the two
side walls 550). The angle of the filter holder slits 566 can
configure the filter 524 to be positioned at an angle relative to
the two side walls 550. When the filter 524 is not substantially
parallel to one or more of the side walls 550, air that flows
through the filter structure 522 may be directed by the fan 528 to
come in contact with a greater area of the filter 524. The more
contact the air has with the filter 524, the more efficient the
evaporative air cooling tower 500 can function. If the angle of the
filter 524 relative to the side walls 550 is 90 degrees (e.g.,
substantially perpendicular to the side walls 550), the filter may
restrict the air flow through the filter structure 522 and decrease
the force of the air exiting the evaporative air cooling tower 500.
In this configuration, the air exiting the evaporative air cooling
tower 500 may be colder but less air may exit at any given time. In
some embodiments, the angle of the filter holder slits 566 is
configured to be adjustable (e.g., the angle can be adjusted to a
greater or a smaller angle). In some embodiments, the angle of the
filter holder slits 566 is fixed (e.g., a predetermined angle).
[0138] The filter holders 544 can be configured to secure the
filter 524. As the filter 524 absorbs and stores the liquid, the
filter 524 may increase in volume and weight. The filter holders
544 can be configured to secure the filter 524 such that the filter
524 substantially maintains its configuration (e.g., does not
substantially sag or become deformed). The filter 524 can be
configured to store the liquid, and as the fan 528 directs air
toward and through the filter structure 522, the absorbed liquid
can cool the air and form a mist that is directed through the grill
506.
[0139] As generally illustrated in FIG. 25D, the filter structure
522 can comprise a top cavity 554. The top cavity 554 can be
positioned adjacent to the top wall 552. The top cavity 554 can
comprise an opening defined by portions of the side walls 550 and
front and back walls of the filter structure 522. As generally
illustrated in FIG. 25C, the top cavity 554 can be configured to
receive a filter tray 570. The filter tray 570 can be coupled to
the top cavity 554. The filter tray 570 can be coupled to the
filter structure 522, such as to the side walls 550, or to any
other portion of the filter structure 522. The filter tray 570 can
be removably coupled to the filter structure 522. The filter tray
570 may comprise tabs that are configured to snap into compartments
of the side walls 550. The filter tray 570 may be configured for a
user to remove or insert the filter structure 522, via the filter
tray 570, out of or into the interior 504 of the housing 502,
respectively. The filter tray 570 may include a depression
configured for removing the filter structure 522 from the interior
504 of the housing 502 and/or to insert the filter structure 522
into the interior 504. In this example, the user can insert a
finger into a portion of the filter tray 570 to remove the filter
structure 522 from the housing 502.
[0140] As generally illustrated in FIG. 25D, the filter structure
522 can comprise a second filter 526. The second filter 526 may
include one or more filters. The second filter 526 can be
positioned within the top cavity 554. The second filter 526 can be
coupled to the filter structure 522. For example, the second filter
526 may be coupled using an adhesive to the side walls 550, or any
other desired coupling. The second filter 526 can be removably
coupled to the filter structure 522. For example, the second filter
526 may be inserted into the top cavity 554. The second filter 526
can be positioned adjacent to the top wall 552 and portions of the
filter 524 (e.g., portions of the filter 524 that loop around the
top bars 560. The second filter 526 can be configured to receive
and absorb liquid from the tray 514 (e.g., from the tray 514,
through the outlet 594, to the filter tray 570, and through the
filter tray openings 572 to the second filter 526). The second
filter 526 can transfer the liquid to the filter 524. Excess liquid
not absorbed by the filters 524, 526 can flow through the interior
504 of the housing 502 and into the tank 510 for re-circulation
within the evaporative air cooling tower 500. The filter structure
522, including the filters 524, 526 can be reusable. The filter
structure 522 and the filters 524, 526 can be washed. The filter
structure 522 and the filters 524, 526 can be replaced. The filters
524, 526 can be soaked in liquid and frozen prior to the filter
structure 522 being inserted into the evaporative air cooling tower
500. When the liquid is frozen onto one or more of the filters 524,
526, the evaporative air cooling tower 500 can be configured to
provide additional cooling (e.g., can cool air more quickly, can
cool the air to a lower temperature, can cool air for a longer
period of time, etc.).
[0141] The second filter 526 can be in fluid communication with the
filter 524 and the filter tray 570. The filter tray 570 can be
configured to receive the liquid from the tray 514. For example,
the tray 514 may comprise an outlet, such as a tray outlet 574. The
tray outlet 574 may be configured to release the liquid from the
tray 514 toward the filter tray 570. The filter tray 570 can define
one or more openings, such as filter tray openings 572. The filter
tray openings 572 can be configured for the liquid to flow through
and onto the filter, such as the second filter 526. The filter tray
openings 572 can be configured to receive liquid from the tray 514.
The filter tray 570 can be configured to distribute the liquid
through an interior of the filter structure 522. For example, the
filter tray 570 can receive the liquid, store the liquid for a
period of time, and distribute the liquid through one or more of
the filter tray openings 572. The liquid can be distributed to one
or more filters. The second filter 526 can distribute the liquid to
the filter 524. The second filter 526 may distribute liquid more
quickly to the filter 524 if the filter 524 has the capacity to
absorb more liquid. At least one of the filter 524 and the second
filter 526 can be formed from a sponge material. The sponge
material may comprise a microbacterial material. The microbacterial
material may contain an antimicrobial agent that inhibits the
ability of microorganisms to grow on the surface of the sponge
material. The evaporative air cooling tower 500 may comprise a
filtration system, such as to filter dirt, dust, hair, small
insets, smells, other pollutants, or combinations thereof from
polluted air flowing into the interior 504. The filter structure
522 may function as the filtration system. At least one of the
filter 524 and the second filter 526 may be formed from material
for filtration. For example, the filters 524, 526 may comprise
filtration material, such as carbon charcoal, silk, any other
desired filtration material, or combination thereof. The filtration
system can be configured to purify the air and expel purified air
from the interior 504.
[0142] The evaporative air cooling tower 500 can comprise a tank
510. The tank 510 can be positioned adjacent to a bottom portion
512 of the housing 502. As generally illustrated in FIG. 22, the
tank 510 can be configured to open. The tank 510 can be removably
coupled to the housing 502. The tank 510 can be configured to open
by entirely and/or partially sliding the tank 510 from the housing
502, by rotating a front face of the tank 510 via a hinge, or by
any other suitable opener. The tank 510 may comprise an indentation
588 in a face 592 of the tank 510. The indentation 588 can be
configured for a user to pull the tank 510 from the housing 502.
The tank 510 can receive liquid, such as water. The tank 510 can
store the liquid. The liquid may include a scent to provide a
desired smell into the room. For example, a scented oil may be
added to the liquid. The scent from the scented oil may be diffused
into the air expelled from the evaporative air cooling tower
500.
[0143] The tank 510 may be operatively coupled to a hose 518 and a
pump 220. The hose 518 may be a cylindrical elongated hose. The
hose 518 can be in fluid communication with the tank 510 and the
tray 514. The pump 520 can be configured to pump fluid through the
hose 518. A first end of the hose 518 can be disposed in the tank
510. A second end of the hose 518 can be disposed in the tray 514
or above the tray 514. The pump 520 can pump the liquid through the
hose 518 from the tank 510 to the tray 514. The liquid can flow
through the outlet 594 of the tray 514 to the filter tray 570. The
pump may be configured to pump water at different speeds. For
example, if the evaporative air cooling tower 500 is turned on to a
high mode, the pump 520 may pump water at a first speed. If the
evaporative air cooling tower 500 is turned on to a low mode, the
pump 520 may pump water at a second speed, such that the first
speed pumps the water at a greater flow rate than at the second
speed. The evaporative air cooling tower 500 may have one or more
sensors that detect liquid levels in the tank 510, the tray 514,
any other suitable compartment, or combination thereof. The
evaporative air cooling tower 500 may be configured to adjust the
rate at which the pump 520 operates so that the tray 514 does not
overflow with liquid. The evaporative air cooling tower 500 may
include one or more windows, such as a tank window 590, configured
to show a liquid level in the tank 510 (e.g., to show that the
liquid level is full, partially full, nearly empty, etc.). The tank
window 590 may be coupled to a front side of the bottom portion 512
of the housing 502. The evaporative air cooling tower 500 may
include one or more lights configured to emit light into the tank
510. The light can be emitted, such as through the tank window 590,
to indicate to the user, a liquid level in the tank 510. The
evaporative air cooling tower 500 may be configured to provide an
alert if the liquid level of the tank 510 is low or empty. The pump
520 may be disposed in and/or coupled to the tank 510. The pump 520
may be disposed within a compartment within the tank 510.
[0144] As generally illustrated in FIG. 26, the fan 528 can be
disposed within the housing 502. The fan 528 can be configured to
spin to generate airflow. The fan 528 may be cylindrical, circular,
or any other desired shape. The fan 528 may comprise a plurality of
blades 584. The plurality of blades 584 may be formed in a
generally curved rectangular shape or any other desired shape. The
fan 528 may comprise blade holders 586. The blade holders 586 may
be formed in a ring shape, any other suitable shape, or combination
thereof. The plurality of blades 584 may be coupled to one or more
blade holders 586. For example, the plurality of blades 584 may be
coupled via adhesive, snaps, received into openings defined by the
blade holders 586, formed with the blade holders 586, or any other
attachment configuration. The fan 528 can be configured to rotate
(e.g., spin) to generate air flow. The fan 528 may be configured to
rotate 360 degrees. As the fan 528 rotates, it directs air in one
or more directions. For example, one or more of the plurality of
blades 584 may be aligned adjacent to one or more of the plurality
of blades 584. The plurality of blades 584 may be coupled to the
blade holders 586 at an angle between 5-85 degrees relative to the
side walls 550 of the housing 502. As the fan 528 spins, it directs
air flow toward a direction correlating with the angle of each of
the blades 584. The fan 528 may comprise one or more sets of the
plurality of blades 584. Each set of the plurality of blades 584
can be coupled to two blade holders 586, one at each end of the
blades 584. For example, for a first set of blades 584, first ends
of the plurality of blades 584 can couple to a first blade holder
586 and opposing second ends of the plurality of blades 584 can
couple to a second blade holder 586. First ends of a second set of
blades 584 can be configured to couple to the second blade holder
586 at an opposing side at which the first set of blades 584
couples to the second blade holder 586. Second ends of the second
set of blades 584 can couple to a third blade holder 586, and so
forth. The fan 528 may comprise one or more sets of the plurality
of blades 584 coupled to blade holders 586. In some embodiments,
the number of sets of the plurality of blades 584 aligns with
corresponding sections of the filter 524. For example, the fan 528
may comprise six sets of the plurality of blades 584 (e.g., each
set of the plurality of blades positioned between two blade holders
586) and the filter structure 522 may comprise six sections of the
filter 524 (e.g., each section of the filter 524 can be defined
between two filter holders 268). The number of sets of the
plurality of blades 584 and the number of sections of the filter
524 described in this disclosure are exemplary and the numbers may
be greater or fewer. The plurality of blades 584 and the blade
holders 586 may be formed from plastic, metal, or any other desired
material.
[0145] The evaporative air cooling tower 500 can operate as a
humidifier. The evaporative air cooling tower 500 can be configured
to receive air with low levels of moisture and output air with
higher levels of moisture. In other words, the evaporative air
cooling tower 500 can add moisture to the air, such as the air in a
room. The evaporative air cooling tower 500 can output a cooling
mist into the ambient air. The water particles that are expelled
into the air can raise the level of moisture in the air.
[0146] The evaporative air cooling tower 500 can comprise one or
more motors 578. The motor 578 can be operatively coupled to the
housing 502. The motor 578 may be configured to rotate the housing
502. For example, the motor 578 may be configured to oscillate the
housing 502. The motor 578 may rotate the housing 502 on a
horizontal axis. For example, the motor 578 may rotate the housing
502 in a first horizontal direction and in a second horizontal
direction. The motor 578 may rotate the housing 502 between 5 and
180 degrees, or any other desired angle of rotation. The one or
more motors 578 may be configured to rotate the fan 528. The
evaporative air cooling tower 500 may include a timer configured to
monitor the amount of time that the motor 578 oscillates the
housing 502. When the time period has elapsed, the motor 578 may
end the oscillation and/or turn off the evaporative air cooling
tower 500. The evaporative air cooling tower 500 may include one or
more buttons 580, as described below, that allow a user to control
one or more operations of the evaporative air cooling tower
500.
[0147] The evaporative air cooling tower 500 can include a safety
interlock 576. The safety interlock 576 can be configured to
prevent operation of the evaporative air cooling tower 500. For
example, if at least one of the grill 506 and the filter structure
522 is removed from the housing 502, the safety interlock 576 can
shut off operation of the evaporative air cooling tower 500. The
safety interlock 576 can function as a safety feature such that a
user does not touch the fan 528 while the fan 528 is spinning in
operation.
[0148] As generally illustrated in FIG. 22, the evaporative air
cooling tower 500 may include one or more buttons 580. The one or
more buttons 580 may be coupled to the housing 502, such as on a
top portion of the evaporative air cooling tower 500. The one or
more buttons 580 can be configured for controlling operations of
the evaporative air cooling tower 500. For example, the one or more
buttons 580 may include: (a) a fan-shaped button configured to
control one or more speeds of the fan 528 (e.g., high, medium, and
low speeds) and when depressed can circulate through the speed
options; (b) a timer, which can be configured to manually set the
fan 528 to operate for a period of time (e.g., two hours, six
hours, eight hours, or twelve hours, etc.); (c) an LED light button
configured to display one or more levels of brightness for lights
602 (e.g., full power, 50% power, off); (d) an oscillation button
configured control the oscillation of the housing 502; or any other
desired button to control features of the evaporative air cooling
tower 500. The evaporative air cooling tower 500 may comprise one
or more lights configured to function as a nightlight, for
ambiance, to provide the user with an indication of an operation,
or any other desired purpose. For example, each time the user
presses the timer button, a corresponding time slot may light up
and remain lit until the chosen time period expires. Similarly, if
the user chooses to turn the evaporative air cooling tower 500 on a
high speed, three lights may be turned on, if a middle speed is
activated, then two lights may turn on, and if a low speed is
activated, then one light may turn on. The lights 602 may be
located at the top portion 516 of the housing 502, such as behind
the first three rows vents 604 of the grill 506, behind the a
window located at the top portion 516, in the interior 504 of the
housing 502, in the tank 510, or any other desired location. The
lights may be one or more colors. The lights 602 may configured to
display a single color, cycle through two or more colors, or any
other desired display.
[0149] As generally illustrated in FIG. 22, the evaporative air
cooling tower 500 may comprise an electrical cord 582. The
electrical cord 582 can be used to power the evaporative air
cooling tower 500. The evaporative air cooling tower 500 may
comprise a rechargeable battery and a charging port. The
evaporative air cooling tower 500 can use the power to operate the
fan 528, the motor 578, one or more lights, any other desired
function, or combination thereof. The base 596 may comprise an
electrical cord holder 598. The electrical cord holder 598 may be
configured to receive a portion of the electrical cord 582.
[0150] In some embodiments, the evaporative air cooling tower 500
is configured for the user to pull out the removable tank 510
located on the bottom portion 512. The pump 520 can be generally
concealed within the tank 510. The user can remove the tank 510,
fill the tank 510 with liquid, such as water, and close the tank
510 (e.g., insert the tank 510 into the bottom portion 512 of the
housing 502. The user can turn on the evaporative air cooling tower
500 by selecting one of the buttons 580 (e.g., an "on" button).
After the button 580 is depressed, the hose 518 that is disposed at
the bottom portion 512 of the housing 502 (e.g., within the tank
510), runs vertically up within the housing 502 to the top portion
516 of the housing 502. The hose 518 can be configured to slowly
drip liquid into a horizontal tray, such as the filter tray 570
attached to the top of the filter structure 522. The liquid will
saturate the filters 524, 526 and/or flow through the interior 504
back into the tank 510 for re-circulation. When the user turns on
the fan 528, the user can select one of the buttons 580 (e.g., a
fan speed button). The button 580 may be configured to turn on one
or more lights. The lights may be configured to emit light behind
the top grill rows. For example, when the button 580 is selected
for a first time to operate the fan 528 at a slow speed, a light is
emitted behind a first row of vents of the grill 506 for
approximately five seconds, or any other desired amount of time.
When the button 580 is selected for a second time to operate the
fan 528 at a medium speed, one or more lights are emitted behind
the first row and a second row of vents of the grill 506 for
approximately five seconds, or any other desired amount of time.
When the button 580 is selected for a third time to operate the fan
528 at a fast speed, one or more lights are emitted behind first,
second, and third rows of vents of the grill 506 for approximately
five seconds, or any other desired amount of time. The button 580
may be selected to oscillate the evaporative air cooling tower 500
(e.g., to horizontally rotate the housing 502). To clean and/or
replace the filter structure 522, the grill 506 and the filter
structure 522 can be removed from the housing 502. The grill 506
can be removed by the user depressing the pull tab 530 located at a
top portion of the grill 506, or any other desired location. After
the grill 506 is removed from the housing, the user can access and
remove the filter structure 522. The filter structure 522,
including the filters 524, 526 may be hand washed, washed in a
dishwasher, or any other washing treatment. The filters 524, 526
may be formed from a sponge material. The sponge material may be
microbial. The filters 524, 526 may be the same filter or separate
filters. The filter 524 may be coiled and/or looped throughout the
filter structure 522. The filters 524, 526 can be in fluid
communication, such that liquid from one filter can be transferred
to the other filter. The filter structure 522 can be discarded and
replaced. The evaporative air cooling tower 500 may include safety
features, such as a built-in safety mechanism (e.g., the safety
interlock 576) that is configured to stop the fan 528 from
rotating. For example, when the grill 506 is removed from the
housing 502, the safety interlock 576 prevents the fan 528 from
rotating.
[0151] The evaporative air cooling tower 500 can include additional
and/or fewer components and is not limited to those illustrated in
the figures.

778. The drawer 778 may include a drawer notch 782 (see FIG. 31) to
secure the structure in place. For example, the structure may be
placed on a top surface of the water tray 780 and between the
outlet vent 738 and the drawer notch 782.
[0163] In some embodiments, the water tray 780 may be angled such
that when the structure is placed on the top surface of the water
tray 780, any water on the water tray 780 may flow in a direction
toward the structure. For example, the water tray 780 may be higher
toward a back end of the drawer 778 than toward a front end of the
drawer. The water tray 780 may be configured for cleaning. For
example, when the drawer 778 is removed from the air cooler 700,
the water tray 780 may be easily accessible for cleaning. The user
may empty any water on the water tray 780, wipe down and dry the
water tray 780, or otherwise clean the water tray 780. Cleaning the
water tray 780 may prevent mold or bacteria from building up on the
water tray 780 or at any other locations in the air cooler 700.
[0164] Referring to FIG. 27, the air cooler 700 may further include
a holder 748 removably attached to the back face 752 of the housing
